In 2020, the State adopted new climate goals, that call for it to:

By 2020, reduce emissions to 1990 levels

By 2030, reduce emissions to 45% below 1990 levels

By 2040, reduce emissions to 70% below 1990 levels

By 2050, reduce emissions to 95% below 1990 levels

The State releases periodic greenhouse gas inventories. The most recent one details emissions from 2018, and shows emissions have been steadily creeping up every year, and from 2017 to 2018 rose by 1.3%.  "Transportation is the largest category of emissions, accounting for 44.9 percent of the total. Residential, commercial and industrial heating (RCI) is second, accounting for 23.8 percent of emissions, and electrical generation is third, accounting for 16.3 percent of emissions." Meeting the 2020 goal, which we won't know for sure until 2020 emissions are calculated, would have required a 10% reduction from 2018 to 2020.

The emissions inventory presents a detailed graph of emissions based on three year averages:

Transportation is the largest source of greenhouse gas emissions, followed by the residential, commercial, and industrial sector (RCI), and then by electricity. Emissions from electricity have been declining in the state, while emissions from transportation and RCI have been increasing, as show in the chart below:

The largest source of transportation emissions is gasoline for on-road vehicles, which is roughly three times larger than emissions from diesel, most of which is from trucking. Emissions from aviation has been growing recently.

Emissions from residential buildings is roughly similar to emissions from commercial (including large multi-family) buildings. Emissions from industry is about twice as much as emissions from residential and commercial buildings combined, and is also growing year to year.
