At a project level, prevailing wind speed/insolation will determine how much wind/solar electricity is produced by a specific renewable energy system, composition of household waste will influence the maximum levels of landfill gas production, which will affect how much can be captured/flared. Performance between interventions could differ due to existing policy frameworks and enabling environments or national circumstances such as geographic remoteness and limited intervention sizes (e.g. in Small Island Developing States (SIDS)) that can inhibit achieving economies of scale. For instance, certain interventions intended to prove the viability of specific technologies in given circumstances or penetrate new markets might lead to lower short-term climate benefits for the same financial input directed towards established technologies, but could still be effective over longer time horizons beyond the lifetime of the project itself.
