Project method

Biomass

Cookstoves – helping families in the developing world who would otherwise cook on open fires. Popular due to co-benefits such as reducing illness from indoor smoke and avoiding knock on effects from deforestation.

Methane capture – methane causes 28x more global warming over 100yrs compared to CO2 so these projects aim to capture it to avoid its release into the atmosphere

REDD+ – forestation projects carefully designed with failure mitigation built in

Small hydro – renewable energy hydro projects replacing fossil fuel burning on s smaller scale to avoid the damage that larger dams can cause to the local environment

Solar – renewable energy solar projects replacing fossil fuel burning

Wind – renewable energy wind projects replacing fossil fuel burning

Portfolio – a variety of projects which may change over time. May be difficult to be sure which are currently used and the standards they meet.

Non-REDD forestation – forestation projects without REDD+ certification. Risk of project failure without mitigation and subsequent adverse attention.
