They Say / I Say by A signal phrase often names the author of the source, gives the publication date in parentheses, and can provide some context in your work.

Here's a sample paragraph with in-text citations (bold is for emphasis only; do not do this in your paper).
In British Columbia, our "carbon tax provides a signal across the economy to reduce emissions while encouraging sustainable economic activity and investment in low-carbon innovation" (Province of British Columbia, n.d., para. 1). How is the price set for each tonne of gas emission? And what are the factors than influence the pricing?
According to Patel (2011) the theory behind carbon pricing is the assumption that the market will price it fairly. This theory ignores the fact that special interest groups, such as oil companies and known industrial polluters, are vocal in their opposition to governments asking for limits to the impact of carbon taxes. Conflicting scientific opinion and uncertainties about climate change and its possible effect are huge, making the economic argument for strict GHG reductions far from clear (Pindyck, 2013, p. 44).
