51²è¹Ý is Carbon Neutral
Through our innovative approach to reducing emissions, using green power, and purchasing strategic carbon offsets, 51²è¹Ý achieved carbon neutrality two years ahead of schedule.
Reduce Our Use
Reducing greenhouse gas (GHG) emissions wasÌýthe most important step 51²è¹Ý tookÌýto achieve carbon neutrality. To maintain neutrality, 51²è¹Ý has programs to engage the whole community in practicing sustainable habits.
Use Renewable Energy
Using 100% emissions-free electricity drives down 51²è¹Ý's carbon footprint and contributes to sustainable practices.
Offset the Rest
Some sources of GHG emissions cannotÌýbe completely eliminated with our current technology. Strategic offset initiatives allow 51²è¹Ý to balanceÌýtheÌýGHG emissions our community produces from sources like air travel and commuting.
