We have now offset another 20,000 ton CO2eq in a Gold Standard certified project!
By distributing cookstove technology to communities in Rwanda, this project benefits the environment by significantly reducing CO2 intense fuel consumption. Health conditions inside homes are improved due to the presence of less indoor smoke, and families can spend less time collecting wood fuel and more time with their families.
Biomass, principally firewood and charcoal, holds huge importance in Rwanda, accounting for a significant proportion of energy consumption. Biomass is often the predominant source of energy for cooking and water boiling, especially in rural areas. Cooking is generally carried out on thermally inefficient traditional devices and produces large amounts of smoke and indoor air pollution.
The replacement fuel-efficient stove will lead to a significant reduction in the annual usage of biomass for users. The improved stove has been designed to balance efficiency, safety, cost, stability and strength with a focus on using locally available materials.
By reducing the consumption of non-renewable wood and providing cookstoves with fuel savings, this project reduces the amount of greenhouse gas emissions into the atmosphere. A decrease of deforestation has a positive impact on biodiversity. Households save money by having less fuel requirements for cooking the same amount of food and health is improved through the reduction of indoor air pollutants from cleaner cookstoves. The project also generates employment and income for people via the distribution and maintenance of the stoves, as well as training and employing community education staff.
Beräkningarna är kompatibla med GHG-protokollet för många mindre tjänsteföretag. Vårt mål har dock inte varit att göra en fullständig scope 3-analys av mer komplexa företag, utan istället göra något som är enkelt för många mindre bolag att göra för att få koll på sina klimatutsläpp.
We have done some research about the carbon footprint of running cloud, data center and on-premise servers.
Our goal has been to find a way to estimate the carbon footprint from the servers we need to calculate emissions for in our business carbon footprint calculator. We wanted to find a good approximation of the emissions without forcing the business to enter everything about the server-model and kWh-consumption they use in our calculator.
This is an attempt to summarize our findings.
We quickly realized that just requiring the number of servers running is a too rough measurement, often resulting in estimations 5-10x lower or higher then a precise calculation. So we needed to require more parameters from our business users to not be too off in our approximation.
After some experimenting and reading we found that there are two factors that both are fairly easy to find out and also make a big impact on the carbon footprint of servers, if the electricity used is green or not and if the servers are in the cloud or not.
Therefor we divide our calculations of the carbon footprint for servers into four categories. More categories could easily be constructed to achieve more precise estimations, but as stated earlier, our goal was also to make this an as easy as possible thing to find out for the business calculating the footprints.
The four categories we ended up with are:
Cloud server using 100% green electricity
Cloud server using non-green electricity
On premise or data center-server using 100% green electricity
On premise or data center-server using non-green electricity
To find out which category to use, you need to know if the electricity your servers are using is 100% green (or if the electricity not green is being offset in a credible way) and if your servers can be considered running in a cloud.
How do I know if the electricity our servers are using is 100% green?
With green electricity we mean fossil free electricity, so both renewable energy sources and nuclear energy are considered green – and are in our calculations considered having a zero climate impact. This is not 100% true since both renewable sources and nuclear sources have a carbon footprint from construction and maintenance, but the climate impact are negligible in comparison with electricity from fossil sources.
Depending on where your servers are located, there are different ways of finding out if the electricity your servers use is green:
On premise-server – check your electricity contract or contact your electricity-provider
Data center-server – check your contract or contact your provider
Cloud server – this is a bit more tricky. But if you want the short answer per provider:
Google Cloud – 100% green
Microsoft Azure – 100% green
Amazon AWS – Non green electricity for all locations except US West (Oregon), Europe (Frankfurt), Europe (Ireland), GovCloud (US-West), Canada (Central). More locations might appear in the future here: https://aws.amazon.com/about-aws/sustainability/
This might sound like an easy question, but there are many local providers that have smaller cloud-like solutions that might be as energy effective and utilize servers as good as the larger ones.
So the question you should ask yourself here – if you are unsure if your servers can be considered being in the cloud or not – is if your provider can utilize servers about as effective as the larger providers and if they can have the same energy efficiency as the larger ones.
The difference between the carbon footprint of servers running in large cloud providers and not can be big. According to the studies we have found on this:
We have decided to apply a simple factor of 0.5 for the energy consumption and server utilization of servers in the cloud. Amazon AWS claims a reduction of 84% in the amount of power required, but since we don’t have data for other providers we are rather a bit more conservative here.
The energy consumption from manufacturing and use
In our carbon footprint business calculator we have chosen to use data from a standard 2019 R640 Dell server. This is deemed as a high end but not unusual server being bought 2019. An exact server model would give more precise data here, but we decided that it was not reasonable to expect people using our business calculator to know the exact name of the servers if the have been bought by the business, and in the cloud it’s close to impossible to know exactly what hardware model your server is run on anyway.
The server is consuming 1760.3 kWh / year and has a manufacturing climate impact of 320 kg CO2e/year assuming a four-year life span.
If you are doing a calculation of your own and you know exactly what kind of server you or your provider uses, you should use those numbers instead.
The Four Carbon Footprint categories
We have used a Nordisk Residualmix as the factor for CO2e emissions per kWh. The factor is 0,329 CO2e / kWh. The reason for us using this is that most business using our calculator are expected to be in the Nordics.
So if we use these number and assumptions from above:
Emissions from production of servers for use on premise: 320 kg CO2e/year
Emissions from production of servers for use in cloud (since 50% is manufactured for use in cloud): 160 kg CO2e/year
Emissions from green power consumption: 0 kg CO2e/year
Emissions from non-green consumption for premise power or self managed servers : 1760.3 kWh / year * 0,329 CO2e / kWh = 579 kg CO2e
From non-green cloud power consumption : 1760.3 kWh / year * 0,329 CO2e / kWh * 0,5 = 290 kg CO2e
This results in these factors four our four categories:
Cloud server using 100% green electricity: 160 kg CO2e / year and server
Cloud server using non-green electricity: 450 kg CO2e / year and server
On premise or data center-server using 100% green electricity: 320 kg CO2e / year and server
On premise or data center-server using non-green electricity: 899 kg CO2e / year and server
Please comment to this post if you have any questions or comments!
To combat climate change, easy access to data about our emissions are necessary. One of the largest sources of emissions for many individuals is the emissions from flying.
The GoClimateNeutral Flight Emissions API calculates an approximation of the amount of CO₂-equivalents a flight emits per person.
We wanted to build the GoClimateNeutral.org Flight Emissions API to educate people searching for flights what the environmental impact is per person, and thereby enabling people to choose less environmentally damaging flights or ways of travel.
We have now offset another 25,000 ton CO2eq in a CDM and Gold Standard certified project!
Located in northern India, this large-scale, 50 MW-capacity solar thermal power project generates almost 119,000 MWh for India’s Combined Regional Grid, displacing electricity sourced from the burning of fossil fuels to reduce emissions and contribute to regional sustainable development.
India is the world’s second largest country by population, beaten only by China – and it is rapidly catching up. As its developing economy strengthens further and rapid population growth continues, India’s energy needs are rising. While the share of renewables in India’s energy mix is growing, coal still accounts for over half of its electricity production.
Located in Jaisalmer District in North India’s Rajasthan State, this large-scale solar thermal power project helps satiate India’s growing energy demands. The 50 MW-capacity solar thermal plant uses parabolic trough technology to generate almost 119,000 MWh of clean energy for the Combined Regional Grid annually, further diversifying India’s electricity mix away from fossil fuels.
On top of supplanting fossil fuels with clean electricity to reduce emissions, the project proponent commits 2% of Carbon Emission Reduction (CER) sales to community welfare and sustainable development projects. The social benefits of this include local employment opportunities that alleviate regional poverty, as well as better roads and improved basic infrastructure. The project also contributes to the transfer of environmentally sound, state-of-the-art thermal solar power generation technology in India, and encourages further technology development.
To carbon offset a company is to take responsibility for the carbon emissions the company produces – and by doing that being part of stopping climate change.
How do I get started?
There’s two alternatives if you want to get started with your carbon offsetting with us at GoClimateNeutral:
Standardized calculations: The standard to calculate carbon emissions from a company is to follow the GHG-protocol (GHG is for Green House Gases). This is something all larger companies should do since it gives you a tool to see how large different emissions are and thereby a possibility to decrease emissions more effectively. Since it’s a standard it also makes it possible to compare your emissions with other companies in the same industry. If you want help with this, contact us at [email protected]
Simple calculation based on number of employees: The cons with GHG-calculations is that they are rather time consuming and therefore costly. To get more companies to take responsibility for their climate footprint we also offer a simpler way to take responsibility for your emissions. It’s based on the mean emissions for one person (11 tonnes CO2eq in Sweden) x a safety factor to be sure we don’t underestimate the emissions (we use a factor of 2) x the number of employees in your company. You can do the calculation here and contact us for more info: https://www.goclimateneutral.org/business
It’s easy to take responsibility for your emissions and to be a part of the solution of climate change. It also has lots of other advantages for the region where the climate project is supported and for your company.
Att klimatkompensera för sitt företag är att ta ansvar för sitt företags klimatutsläpp, och därmed vara med och stoppa klimatförändringarna.
Hur kommer jag igång?
Det finns två alternativ om du vill komma igång, dels kan vi hjälpa till med standardiserade men lite omständigare beräkningar, men vi kan också erbjuda ett enkelt sätt att komma igång med direkt.
Standardiserade beräkningar: Det standardiserade sättet att som företag beräkna sina utsläpp är att göra en beräkning enligt det så kallade GHG-protollet (GHG står för Green House Gases). Det här är något som alla större företag bör göra, då det ger en verktyg att se hur stora alla olika utsläpp är, vilket i sin tur gör det möjligt att minska de utsläpp som är störst. En annan fördel med GHG-beräkningar är att det är en standard, vilket gör det möjligt att jämföra ens egna utsläpp med andra företag i branschen. Vi hjälper gärna till med det för tjänsteföretag, kontakta gärna oss på [email protected] för mer information.
Enkel beräkning baserat på antal anställda: Nackdelarna med GHG-beräkningar är att de är tidskrävande och därmed kostsamma – och ändå inte blir helt exakta. För att få fler att ta steget att ta ansvar för sina utsläpp så erbjuder vi ett enklare sätt att komma igång med att ta ansvar för sina klimatutsläpp. Detta bygger istället på hur många anställda man är (som är helt korrelerat med utsläppen för de allra flesta tjänsteföretag). Beräkningarna bygger på medelutsläppet för en svensk per år (11 ton CO2eq) x en säkerhetsfaktor för att vara på den säkra sidan (vi använder oss av en dubbling, dvs faktor 2) x antalet anställda. Du kan göra beräkningen och intresseanmälan här: https://www.goclimateneutral.org/business
Det är enkelt att komma igång med att ta ansvar för era klimatutsläpp och vara med och stoppa klimatförändringarna – vilket dessutom har många andra fördelar för regionen där klimatprojektet stöttas och för erat företag.
We have for the second time invested in the Gold Standard-certified CDM-project Nanyang Danjiang River Solar Cooker Project and contributed to preventing 15 000 ton of CO2 from reaching the atmosphere. Thank you so much everyone for contributing to a cleaner and greener future!
The Nanyang Solar Project improves the indoor hygiene and living conditions of 48,000 rural households in one of the poorest regions in China. By replacing traditional coal-fired cooking stoves with clean solar cookers – CO2-emissions are reduced and the quality of life of 48,000 rural household are improved.
In the rural area of Xichuan County, Henan Province it is estimated that 76.4% of local households use coal-fired stoves as the main energy source for their daily lives. Not only do these coal stoves create harmful carbon emissions, but the large amount of wood and coal fuel they require is in dwindling supply.
The Nanyang Danjiang Solar Cooker Project enables these rural households to substitute traditional coal stoves for a solar energy alternative. 48,000 of these stoves have been distributed to seven towns in the Xichuan County, Henan Province. They are 50% more efficient than traditional coal stoves and, with an energy capacity of 876.5 W per unit, displace the CO2 that would have been generated by the fossil fuel consumption of coal fires.
With access to solar cooker methods, local residents now have a cleaner, practical and more efficient way to meet the energy demand of their daily cooking. By switching to solar power, health issues related to the excess soot and indoor smoke-pollution of coal fires have been abated. The solar cookers are distributed and maintained by the project for free, and because they no longer have to purchase coal fuel, villagers can use the money saved to buy things that improve their standard of living.
We have now offset another 15000 ton CO2eq in a CDM and Gold Standard certified project! A big thank you to all our more than 2400 users for making this possible!
We have offset via the Za Hung Hydropower project before, you can read about that time here. Za Hung Hydropower is a small scale hydropower project situated at the A Vuong River in the Quang Nam province, in the South Central region of Vietnam. With an electricity generation of 114,079 MWh per year, the plant contributes to bridging the supply-demand gap in the region and improves the livelihoods of local communities where minority ethnic groups live.
We have now offset another 15 000 ton CO2eq in another CDM and Gold Standard certified project! A big thank you to all our more than 2300 users for making this possible!
The Bangna Starch Wastewater Treatment and Biogas Utilization Project takes care of harmful and odorous methane emissions from wastewater. The methane have been cleverly repurposed to generate biogas energy at a Cassava starch plant in the Kalasin Province. This has greatly improved the air quality in the area, and created new training and job opportunities for local workers.
Embedded in the forests at the foot of the Phu Pan hills, the Kalasin Province region is typified by agriculture. The growth and processing of Cassava starch is a huge aspect of the economy here. However these starch processing factories place significant strain on the environment, requiring a high demand of water for washing the cassava, with pungently odoured methane emissions and high fossil fuel reliance. The Bangna Biogas Project neatly addresses all of these environmental issues by replacing the old cascading open anaerobic lagoon treatment system with a modern Upflow Anaerobic Sludge Blanket (UASB) reactor system. It captures biogas from plant wastewater that would have previously been emitted into the atmosphere, instead using it to replace fossil fuels to generate electricity which is then exported to the national grid. In addition to this, the treated wastewater can now be recycled and used for cleaning the cassava, which saves many tonnes of fresh water per day.
For the local community, the air quality has improved vastly, special training opportunities have been provided and several permanent jobs created to operate and maintain the biogas facilities.
UN Sustainable Development Goals that the project also contributes to:
Treated wastewater can be recycled for washing cassava
8800 MWh of clean electricity is generated yearly
22 permanent jobs created including 15 from the local area
